Sea to Summit First Aid Dry Sack Review

This is the second dedicated first aid pack I own in this family having previously purchased the 1 litre size. I discovered that the smaller pack that while I could fit all my first aid requirements into the 1 litre size, there wasn’t enough pack left to roll over the top to provide a water proof seal. So I relegated the smaller pack to become my first aid kit for my day hikes; funny that because that’s what its sold as! The 3 litre pack is sold as an overnight first aid kit and while it performs that function well I can also fit my toiletries comfortably into this larger size. The extra materials for me between a day hike and overnight hike are:

  • Tooth brushing materials
  • Feet taping materials
  • Bathing materials

Everything else remains the same because in all honesty if I’m going to sustain an injury on-trail, it really doesn’t matter about the length of the hike.

Many people may ask why bother having a dedicated pack for your first aid gear. The small dry bag I have been using for the past six years has been a non dedicated packing cell similar to others I use for other gear that I want to keep all in one place. My first aid gear always sits at the top of the pack so if I do need it in an emergency then I know where it’s located. The other identical packing cell which stores my voice recorder sits in a different part of my pack so there is limited chance of confusion. Where I do mix up these two identical packs is in my tent when I have both of these packs sitting just above my head and I regularly reach for the wrong one. The other consideration for choosing a clearly marked first aid kit is that in the event that someone has to access your pack to treat you, it’s important to make it easy for them.

So I decided to change things up and went looking for a dedicated unique pack for my first aid supplies and came across the Sea to Summit First Aid Dry Sack which I pre-ordered in advance of its release. This pack comes in three sizes:

Each of these packs is identical apart from the size and they all come in a bright orange-red colour with a green and white cross with the text ‘First Aid’ printed on it. This pack also comes with a small clear viewing window that allows you to see into the pack and given I don’t own any other storage packs with this type of window, this is also a feature that makes it stand out. As mentioned, I first opted for the 1 litre size which is big enough (just) and while it does fit my full range of first aid supplies and toiletries I carry on my longer hikes including my foot taping for long distance hikes, to get a  better ‘roll’ on the top to keep moisture out a slight bigger size would have been more suitable. As such I now have two seperate first aid kits, one for my day hikes (1 lites size) and one multi-day/long distance hikes (3 litre size). Which sizing you choose will very much depend on what you carry.

Sea to Summit make storage packs with lighter weight material but in this case they have used a 70 Denier fabric so the 1 litre size weighs 36 grams which is relatively lightweight and also very durable. The inside of the pack is also white which is unique and allows for better visibility when rummaging around inside the pack in low light.

This pack comes with a roll top to minimise water and moisture entry, a clip closure to keep everything in place, and a D-ring that allows you to attach it externally to your main pack or to hang it at the campsite. From my perspective the D-ring isn’t something I am likely to use.

The roll top packs are fairly water resistant and almost waterproof if closed properly but I would avoid submersing it as there is always the risk that water may leak in. This closure system will however protect everything from water in all but a sustained submersion.

This is a handy little pack for first aid gear but also one that can be used for storing other items if the need arises. If you do decide to purchase one of these nifty little storage sacks, first work out what you are carrying from a first aid perspective so you can opt for the right size.
